[Theory-seminars] Seminar 11 a.m. Wednesday, January 4 (NOTE THE TIME)

[Alexei Prokudin]

Dear all,
we will have several interviews of candidates for postdoc positions at 
theory center.

The first one will be this Wednesday the 4th of January.

*11 A.M. F213*

Speaker: Lingyun Dai (Peking University, China)

Title: Study of Effective Field Theories on low energy
QCD

Abstract: After a brief self introduction, we mainly discuss the research on
Effective Field theories on low energy QCD, including Chiral
perturbation theory, Resonance Chiral theory and QCD constraint on
Chiral theories. The first work is to unitarize 1-loop Chiral perturbation
amplitudes, fit them to the phase shift, cross section data and trace
the pole positions in variation of Nc . The result is interesting and
helpful to distinguishing property of mesons. In the second work, we
use R\chiT to calculate the processes of e + e- ? pi+pi-pi0.
PHOKHARA7.0 is used to generate soft (hard) photons in the initial
state, too. The third one is the main work I do now, matching
correlation functions between QCD sum rules and Chiral theories.
Through the matching we want to get constraint on the unknown
constants in Chiral theories.
 
Presentation via phone conference. 

Best,
  Alexei.
